`int dx/(e^x-1)`

Evaluate: int_(-pi)^pi(xsinx dx)/(e^x+1)

Evaluate: int_(-pi)^pi(xsinx dx)/(e^x+1)

l=int(dx)/(1+e^(x)) is equal to

STATEMENT-1 : int(dx)/(e^(x)+e^(-x)+2)=-(1)/(e^(x)+1)+c and STATEMENT-2 : int(d(f(x)))/((f(x))^(2))=-(1)/(f(x))+c

Evaluate : int(1)/(e^(x)-1)dx

inte^x/((1+e^x)(e+e^x))dx

int_0^1(e^x dx)/(1+e^x)

(iii) int(e^(x)-1)/(1-e^(-x))dx

int(1)/(e^(x)+1)dx

Evaluate: int1/(e^x+1)\ dx
